Abstract
Description
Die Erfindung betrifft ein Bypassventil für einen Ölfilter, insbesondere Hydraulikölfilter, mit einer die Öffnung des Stützrohrs des Ölfilters an dessen einem Ende verschließenden Abdeckung, die einen zu der Öffnung ausgerichteten Bypassdurchgang aufweist, einem den Bypassdurchgang verschließenden Ventilkörper und einer Feder, die mit einem Ende am Ventilkörper und mit dem anderen Ende an einem mit der Abdeckung verbundenen Gegenhalter anliegt.The The invention relates to a bypass valve for an oil filter, in particular a hydraulic oil filter, with one the opening of the support tube of the oil filter closing at one end Cover, one to the opening aligned bypass passage, one the bypass passage closing valve body and a spring, with one end on the valve body and with the other end abuts against a counterpart connected to the cover.
Bekanntermaßen öffnen solche Bypassventile, wenn der Druck im Außengehäuse des Ölfilters unzulässig ansteigt, z. B. weil sich das Filterelement, welches das Stützrohr umgibt, zugesetzt hat. Indem das Öl unter Umgehung des Filterelements direkt in den Innenraum des Stützrohrs strömen kann, fällt der Druck im Außengehäuse dann wieder ab.As is known, such open Bypass valves when the pressure in the outer casing of the oil filter rises inadmissibly, z. B. because the filter element surrounding the support tube, added. By the oil bypassing the filter element directly into the interior of the support tube stream can, falls the pressure in the outer housing then again.
Herkömmlich bestehen zwischen der Abdeckung und dem in das Stützrohr hineinragenden Gegenhalter mehrere Punktschweißverbindungen. An den Schweißstellen ist die dem Öl zugewandte Materialoberfläche beeinträchtigt. Insbesondere sind veredelnde Überzüge aus Zink, Zinn, Chrom, Phosphat, Kupfer oder dergleichen zerstört, so dass es dort verstärkt zu Korrosion kommt. Nachteilig gelangt von den Korrosionsstellen abgelöstes Material in den Ölkreislauf. Je nach Materialpaarung kann es auch zur Korrosion unmittelbar im Verbindungsbereich und zum Lösen der Punktschweißverbindung kommen.Conventionally exist between the cover and the protuberance projecting into the support tube several spot welded joints. At the welds is the oil facing material surface impaired. In particular, finishing coatings of zinc, Destroyed tin, chromium, phosphate, copper or the like, so that strengthen it there comes to corrosion. The disadvantage comes from the corrosion spots peelings Material in the oil circuit. Depending on the material combination, it can also be used directly for corrosion Connection area and to release the spot welded joint come.
Der Erfindung liegt die Aufgabe zugrunde, ein in seiner Funktionssicherheit verbessertes Bypassventil der eingangs erwähnten Art zu schaffen.Of the Invention is based on the object, one in its reliability To provide improved bypass valve of the type mentioned.
Das diese Aufgabe lösende Bypassventil nach der Erfindung ist dadurch gekennzeichnet, dass der Gegenhalter mit der Abdeckung durch ineinander greifende Ausbuchtungen, welche in aneinander anliegenden Materiallagen der Abdeckung und des Gegenhalters gebildet sind, verbunden ist.The solving this task Bypass valve according to the invention is characterized in that the Counterholder with the cover by interlocking bulges, which in adjoining material layers of the cover and are formed of the counter-holder is connected.
Vorteilhaft weist ein solches Bypassventil nach der Erfindung unabhängig von der Materialpaarung eine korrosionsfreie und sichere Verbindung zwischen der Abdeckung und dem Gegenhalter auf.Advantageous has such a bypass valve according to the invention independently of the material pairing a corrosion-free and secure connection between the cover and the anvil.
Vorzugsweise sind die Ausbuchtungen gemeinsam in eine Vertiefung in einem Formwerkzeug hinein tiefgezogen.Preferably the bulges are together in a recess in a mold into it deep-drawn.
Insbesondere weiten sich die Ausbuchtungen mit zunehmender Tiefe auf, so dass sie formschlüssig ineinander greifen.Especially The bulges expand with increasing depth, so that they are form-fitting mesh.
Vorzugsweise sind die Ausbuchtungen durch Zusammenpressen aneinander anliegender Böden der Ausbuchtungen aufgeweitet, wobei die Ausbuchtungen insbesondere topfförmig ausgebildet sind und durch Zusammenpressen der aneinander liegenden Topfböden aufgeweitet sind.Preferably are the bulges by pressing against each other Floors of the Bulges widened, with the bulges in particular cup-shaped are formed and expanded by compressing the adjacent pot bottoms are.
Zweckmäßig werden die aneinander liegenden Materiallagen durch einen Pressstempel, welcher einer Vertiefung in einem Formwerkzeug gegenüberliegt, in die Vertiefung hinein tiefgezogen, wobei der Pressstempel in einer Endphase die Topfböden der gebildeten Ausbuchtungen breit drückt und dadurch für die genannte Aufweitung sorgt.Be useful the adjacent layers of material by a press stamp, which is opposite a recess in a mold, deep-drawn into the depression, the press die in a final phase the pot bottoms of formed bulges broadly and thereby for the mentioned Expansion.
Vorzugsweise weist der Gegenhalter eine U-Form auf und ist über flanschartige Abwinklungen an den freien Enden der U-Schenkel mit der Abdeckung verbunden.Preferably has the counter-holder on a U-shape and is on flange-like bends the free ends of the U-legs connected to the cover.
Zweckmäßig sind die Abdeckung, der Bypassdurchgang, der Ventilkörper und/oder die Feder koaxial zu dem Stützrohr angeordnet. Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels und der beiliegenden, sich auf dieses Ausführungsbeispiel beziehenden Zeichnungen näher erläutert. Es zeigen:Are useful the cover, the bypass passage, the valve body and / or the spring coaxial to the support tube arranged. The invention will be described below with reference to an embodiment and the accompanying, relating to this embodiment Drawings closer explained. Show it:
